LVFS says there is a firmware update for my Logitech Unifying Receiver, RQR12.10_B0032 uploaded 2019-9-19 and rated high urgency.
Gnome Software does not find any firmware updates but running fwupdmgr get-devices returns:

I believe I saw firmware version RQR12.09_B0030 firmware discussed in a 2017 thread somewhere.
Running either fwupdmgr get-updates or fwpudmgr update returns:
No releases found for device: Not compatible with bootloader version: failed predicate [BOT01.0[0-3]_* regex BOT01.04_B0016]
Operating system is Ubuntu 19.10. I do not understand what bootloader is referenced in the message.
In the LVFS Security notes for RQR12.10_B0032 it states, "Firmware cannot be verified after flashing." Does this mean the firmware upgrade won't show up even if it has occurred?
I've been using linux for a dozen years. I am comfortable using the Terminal if instructions are clear. If there is a recommended cure, please keep it simple for me.
PS: I have reviewed the May 2018 thread labeled Can't upgrade Logitech unify Firmware using fwupd but my scenario seems very different in every way.
